APPLICATION
The P20Z transducer is destined for a continuous conversion of the RMS current
or ac voltage without a constant component into a constant-current or
constant-voltage standard signal.
The transducer output signal is galvanic isolated from the input signal and
supply. The transducer housing is made of a plastic. On the transducer
outside, there are inseparable screw or socket-plug terminal strips.
TRANSDUCER SET
The set of the P20 transducer is composed of:
- P20Z transducer 1 pc.
When unpacking the transducer, please check whether the type and execution code on the data plate correspond to the order.
BASIC REQUIREMENTS and OPERATIONAL SAFETY
In the safety service scope, the transducer meets the requirements of the EN
61010-1 standard.
Observations concerning the operational safety
- All operations concerning transport, installation, and commissioning as well as maintenance, must be carried out by qualified, skilled personnel, and national regulations for the prevention of accidents must be observed.
- Before switching the transducer on, one must check the correctness of connection to the network.
- Do not connect the transducer to the network through an autotransformer.
- Before removing the transducer housing, one must switch the supply off and disconnect measuring circuits.
- The removal of the meter housing during the guarantee contract period may cause its cancellation.
- The P20Z transducer is destined to be installed and used in industrial electromagnetic environment conditions.
- One must remember that in the building installation a switch or a circuit-breaker should be installed. This switch should be located near the device, easy accessible by the operator, and suitably marked.c
INSTALLATION
4.1 Fitting.
The P20Z transducer is adapted to be mounted on a 35 mm rail acc. to EN 60715.
The overall drawing and the fitting way are presented on the fig.1.
4.2. External connection diagrams
One must carry out external connections with wires of maximal diameters:
– 2,5 mm²for socket-plug executions,
– 1,5 mm² for screw executions.

MAINTENANCE and GUARANTEE
The P20Z transducer does not require any periodical maintenance.
In case of some incorrect operations:
After the dispatch date and in the period stated in the guarantee card:
One should return the instrument to the Manufacturer’s Quality Inspection
Dept. If the instrument has been used in compliance with the instructions, we
warrant to repair it free of charge.The disassembling of the housing causes
the cancellation of the granted guarantee.
